ABSTRACT:
A method for easily performing of centering operation is provided. A lens holder includes a lens barrel and an optical lens. Plural recessed portions are formed in the outer circumference of the lens barrel at regular intervals circumferentially. The recessed portions are recessed toward an inner circumference having a diameter greater than the outside diameter of the optical lens. When a centering operation is performed, the optical lens is mounted into the lens barrel, and then heated adjusting elements are inserted into the recessed portions from the outer circumference of the lens barrel. Thin-walled portions between the bottom surfaces of the recessed portions and the inner circumference are thermally deformed toward the optical lens and thus pushed against the lens. The amounts of insertion of the adjusting elements are adjusted separately, thus centering the optical lens.
